Abstract

(57) [Abstract] [Purpose] The present invention forms a ring portion by binding a bundle of paper with binding holes formed by a punching machine or the like with a flexible pipe and a flexible rod, without cutting the tip of the binding tool. The purpose is to form a grip part with the binding device itself, and to make it easy to carry in a stool. [Structure] A flange is formed at one end of a flexible pipe that fits into a binding hole punched in a bundle of paper, and a flexible rod is connected to the other end of the flexible pipe. A paper bundle binding tool which is formed so that the engaging projection is press-fitted to the flexible pipe, integrally locked, and can be removed by pulling strongly.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper bundle binding tool that binds a paper bundle having a binding hole formed by a punching machine or the like.

[0002]

[Prior art]

 Japanese Patent Laid-Open No. 62-218197 has been known as a binding tool for a columnar body that binds a bundle of paper punched by a punching machine or the like. In FIG. 4 of the publication, a columnar male body in which male flange portions having a diameter larger than the diameter of the bored holes are formed at one end and male teeth (engaging protrusions) are formed on the side surfaces at equal intervals are shown. A binding device including a member and a female member in which a female tooth that meshes with the male tooth and a female brim portion are formed is disclosed.

Next, the usage method will be described. First of all, the male member is inserted into the hole punched by a punch or the like. Then, the female member is inserted into the male member until the female collar portion contacts the sheet bundle. At this time, since the male teeth and the female teeth mesh with each other, the sheets are bound with a certain degree of fitting force (locking force). Finally, the extra male member protruding from the female member is cut.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, it is necessary to cut an extra male member protruding from the female member after binding with the binding tool, and a cutting tool such as scissors or a cutter must be prepared, which is troublesome. It was a thing.

Further, when carrying a bound paper bundle by hand, there is no problem if the bound paper bundle is thin, but if the bound paper bundle is thick, it is not only difficult to carry, but also touching with a hand (finger). There was a problem that the uppermost paper and the lowermost paper that were present were damaged from the binding part.

[0006]

The present invention aims to solve the above problems, and a flange is formed at one end of a flexible pipe that fits into a binding hole formed in a bundle of paper, and a flexible rod is provided at the other end. Are formed in series, and an engaging projection is formed from the tip of the outer circumference of the flexible rod for a predetermined length. The engaging projection is press-fitted to the flexible pipe to integrally lock, and it can be pulled out by pulling strongly. It is characterized by doing so.

【Example】

 FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 is a sheet bundle, and 2 is its binding hole. 3 is a flexible pipe made of a flexible material such as polypropylene that fits into the binding hole 2, and has a collar 4 formed at one end. Reference numeral 5 is a flexible rod continuously provided at the other end of the flexible pipe 3, and an engaging projection 6 is formed from the tip of the outer periphery thereof to a predetermined length, and the flexible rod 5 is press-fitted to the flexible pipe 3. It is locked together and can be pulled out by pulling strongly.

Next, the usage method will be described. As shown in FIG. 1, the flexible rod 5 is inserted into the binding hole 2 of the sheet bundle 1, the flexible pipe 3 is fitted into the binding hole 2, and the collar 4 is brought into contact with the upper end of the binding hole 2. Next, the flexible rod 5 is press-fitted into the flexible pipe 3, and the flexible pipe 3 and the flexible rod 5 form a ring portion.

FIG. 2 shows a second embodiment of the present invention. Reference numeral 10 is a flexible pipe made of a flexible material such as polypropylene that fits into the binding hole 2. A flange 11 is formed at one end, and an engaging projection 12 is provided on the outer periphery of the flexible pipe 10 at a certain length from the vicinity of the flange 11. Has been formed. Reference numeral 13 is a flexible rod connected to the other end of the flexible pipe 10, and an engaging projection 14 is formed from the tip of the outer periphery thereof for a predetermined length, and the flexible rod 13 is press-fitted to the flexible pipe 10. It is locked together and can be pulled out by pulling it strongly. Reference numeral 15 is a retaining ring fitted into the flexible pipe 10.

Next, the usage method will be described. The retaining ring 15 is removed from the flexible pipe 10, the flexible rod 13 is inserted into the binding hole 2 of the sheet bundle 1 as shown in FIG. 2, and the engaging projection 12 of the flexible pipe 10 is pressed against the binding hole 2. Fit and lock the collar 11 against the upper end of the binding hole 2. Next, the stop ring 15 is fitted into the flexible pipe 10 from the tip of the flexible rod 13 and press-fitted into the engaging projection 12 of the flexible pipe 10 projecting from the lower surface of the paper bundle 1 to lock the paper bundle 1 into the collar 11. Put on the retaining ring 15. Next, the flexible rod 13 is press-fitted into the flexible pipe 10, and the flexible pipe 10 and the flexible rod 13 form a ring portion.

[0011]

[Effect of device]

 According to the present invention, a flange is formed at one end of a flexible pipe that fits into a binding hole punched in a bundle of paper, and a flexible rod is connected to the other end of the flexible pipe, and a predetermined length is engaged from the tip of the outer periphery of the flexible rod. A protrusion is formed, and the engaging protrusion is press-fitted to the flexible pipe and integrally locked, and it can be pulled out by pulling strongly, so that the extra portion of the flexible rod can be removed without cutting it. The binding device itself can be used as a grip portion if necessary, and a binding device convenient for carrying can be provided.
